摘要
In a nano-ridge waveguide under oblique illumination, we demonstrated transmission enhancement resulting from a hybrid effect between propagation modes and surface plasmon wave. The measured near-field intensity with 44-degree illumination was 1.6 times higher than that illuminated with normal incident light. Consequently, a wedge-shaped fiber probe was proposed to serve as a compact near-field light source.
